owing to be a full, clear, and exact description of the invcntion, suchas will enable others skilled in l the art to wlnch it appertains tomake and use the same. I

My invention relates to an improved manner of attaching and detaching apneumatic or solid tire to a Vehicle wheel to facilitatc the removal ofboth the tire from the wheel and the inner air tube from the cover: themanner of attaching and removing the tire is equall up li-:,able tosolid tires.

To enable my invention to be fully understood, i will proceed to fullydescribe the some with aid oi the accompanying dranings.

l ie-urc Ii illustrates a side View of a Wheel conmleic according tothis invention, Fig. 2, a. side View oi'tire rim and tire detached fromwheel. Fig. 3, a side View of wheel with tire rim detached and fittedwith a securing; lire. Fig. 4 a cross section of the securing tire drawnon a larger scale. Fig. 5

a front. View of a segment of securing tire. Fig. 6 cross section oftire run and tire drawn to a larger scale showing a preferred lockinganan cment for the divided run.

i a similar VlLW of preceding figure unlocked with tube removed. Fig. 8a similow to F 6 showing a modified form of lot-kin devi Fig. 9 adetached View of a sec-u: ig -croi Wedge.

in cari 'ing the invention into practice I take a suitable whe :1 suchis shown at Fig. 3 and secure upon the oeriphery of the folly r1 strongmetal v the flange ti being higher than 0; these flanges form a circulari secure the tire rimf. in the flange c onces apart, I form notches e. iprovide a tire rim fof special construction as hcresiicr explained, tocarry the outer tire 9. Upon the inside of this tire rim f 1 form orsecure blocks it of a size to into the notches 8 when the tire rim isput on the wheel. @ne side of tire rim and blocks coming against theinside of flange (Z, the tire rim f being then turned a short distanceroundfor the blocks J6 to lock between-the flanges c, (Z. It will beunderstood that the band with thrown up side i diameter of the -hire rimf 'm slightly iargcr than. the diameter offlange r: so that the tire rimcan over it. Fitted-between the flanges c, d, are hearing blocksi (seeFig. 4) the top coming ilush with the top of flange 0. Epon the top ofthese bearing blocks the inside-of tire rim f bears. L' on the tire rimbeing put on the wheel and. turned a short distance as described, oneend of each of the blocks A will come against one of the bearing blocks2' when a Wedge it is passed into the notches e so rcventing the tirerimf turning back, and this locking the tire rim "to the wheel. Tosecure the wedge it is formed with a tag; end Z which projects throughthe flange (Z and is retained by a split'cooter.

To remove the tire rim with tire g, it is only necessary to draw out thewedges it and turn the rim sulliciently back for the blocks ll to comeopposite the notches (2 when the tire rim can be laterally pulled offthe wheel over the top of flange c.

To enable the inner tube to he easily got at and removed, 1 form thetire rimfof two parts which are preferred to be locked together when therim is to be put on the wheel with the air tube inflated. Ifthe locksare not used then the air tube can only be inflated after the tire rimis locked on fish-e Wheel.

Figs. 6 and 7 illustrate suitable locking means at 12. These locks arecountersunk on the outside of blocks it. The form of lock and blockshown at 8, consists of a plate 0 with projecting pegs which take intoc0rresponding holes in the inside of tire rirnf and is secured by asecurity bolt passing from inside of cover 9 through the plate 0 andheld by These dates 0 can be made to form the blocks A Having nowdescribed my invention, What l ilcsire to secure by Letters Patent ofthe lTniti-d States is.--

1. The combination of a wheel, a. band on the exterior thereof havingside flanges of unctual heights. one of said flanges being notched anrlthc other slotted, of. carqiing a tire and provided with internalprojections of substantially the same size as said notches, and wedgesfitting, in said notches, substantially as described.
